Description

EC double-winding dc. brushless motors
Technical field
The present invention relates to a kind of DC brushless motors, refer in particular to a kind of EC double-winding dc. brushless motors.
Background technology
The performance of dc motor is best in various servomotors, its small, efficient, big, starting of contributing Torque is big, dynamic property is good, easy to control.Therefore in high-precision, high performance servo-control system, often with direct current generator To drive executive component.Brushless direct current motor is to substitute the one of brush and commutator with electronics reversing switch and position sensor Kind novel direct-current motor.It is made of controller, rotor-position detection and motor body three parts, is electronic technology and motor The married product of technology.It has efficient, speed-regulating range width, starts rapidly, mechanical property and control characteristic are good, the service life It is long, easy to maintain, reliability is high, the features such as low noise, non-commutation spark and radio interference.But the work of brushless direct current motor Extraneous control is depended on, including is driven forward, reverse drive and rotating speed control etc..
Current EC motors are used for hot environment in motor（30 DEG C or more）When, it is easy to happen alternate winding punch-through, Cause motor cisco unity malfunction.
Invention content
It is an object of the invention in view of the above-mentioned defects in the prior art and insufficient, a kind of resistance to breakdown of winding is provided, is used The EC double-winding dc. brushless motors of long lifespan.
To achieve the above object, the present invention adopts the following technical scheme that：
A kind of EC double-winding dc. brushless motors, including winding bobbin, driving circuit, the driving circuit include that power supply is defeated Enter, protect the triggering electricity of circuit, rectification circuit, regulator circuit, amplifying circuit, winding and the technotron of control positive and negative rotation Road, the winding bobbin winding portion are equipped with barrier wall, winding bobbin are divided into two parts, two phase windings are rotating around two End.After two phase windings separate, double winding EC motors can be used in hot environment, and winding is not easy to puncture.
Further, the winding bobbin is integrally formed for polyhexamethylene adipamide.It can also keep in higher temperature Stronger strength and stiffness, and sticky relatively low, good fluidity.
Further, the winding bobbin is the polyhexamethylene adipamide containing 30% glass.Polyhexamethylene adipamide is received Shrinkage is larger, between 1% to 2%, after having added glass, can reduce shrinking percentage, and shrinking percentage is made to be less than 1%.
Further, the winding bobbin is a rectangular-shape skeleton on the whole, and the endface at skeleton both ends is equipped with barricade And metal wound wire end.The barricade of the endface at skeleton both ends prevents winding to be scattered for blocking winding.
Further, winding protection circuit is equipped between described two windings.By the way that protection circuit is arranged between winding, The instantaneous pressure generated when two-phase break-make is discharged, breakdown damage field-effect tube is avoided, avoids electrical fault.
Further, the winding protection circuit includes a zener diode and two backward diodeds.Electric current passes through The high pressure generated to moment through zener diode after two backward diodeds discharges, and holding circuit voltage stabilization avoids height Pressure breakdown field-effect tube.
Further, include two zener diodes in the trigger circuit of the technotron of the control positive and negative rotation.
The beneficial effects of the invention are as follows：（1）After two phase windings separate, double winding EC motors can be used in hot environment, Winding is not easy to puncture；（2）Improved by driving circuit, eliminates two phase windings and separate solely around the high pressure of generation.
Description of the drawings
Fig. 1 is the winding bobbin schematic diagram of the present invention；
Fig. 2 is the driver circuit schematic diagram of the present invention；
Fig. 3 is the driver circuit schematic diagram of the prior art.
Specific implementation mode
The present invention is further elaborated below in conjunction with the accompanying drawings.
It is the winding bobbin schematic diagram of the present invention in Fig. 1.By the barrier among winding bobbin, two phase windings is made to separate. The winding bobbin uses the polyhexamethylene adipamide containing 30% glass to be integrally formed, and can also keep stronger in higher temperature Strength and stiffness, and sticky relatively low, good fluidity.
As shown in Fig. 2, the driving circuit includes power input, protection circuit, rectification circuit, regulator circuit, amplification electricity Road, winding and control positive and negative rotation technotron trigger circuit, winding protection circuit is equipped between described two windings. After power supply input circuit, by protecting circuit and rectification circuit and regulator circuit, after transistor amplifier, by controlling just The positive and negative rotation of the trigger circuit control winding of the technotron of reversion increases winding protection circuit between two windings, The winding protection circuit includes a zener diode and two backward diodeds.Electric current after two backward diodeds by passing through The high pressure that zener diode generates moment discharges, and holding circuit voltage stabilization avoids high-voltage breakdown field-effect tube.And Increase a zener diode in the trigger circuit of the technotron of original control positive and negative rotation.
Above-described embodiment only lists the preferable embodiment of the present invention, protection domain not for the purpose of limiting the invention, In every case the equivalence changes done within the scope of the present invention and modification, should all fall into protection scope of the present invention.
